The most interesting thing about the signing is that it shows Guardiola's putting all his eggs in the "all-out attack" basket. Whether that will work in the Prem remains to be seen (to say the least). I wonder whether he'll survive if they don't win either the Prem or Bigears next season.
The interesting thing with Guardiola is they spent about 4 years chasing him, building the set up around his preferred way of working. If he walks or he gets sacked, and with Guardiola one is as likely as the other, where do the go from there
